AUTOMATIC STUFFING MACHNE.

Application led June 29, 1921. Serial No. 431,362.

To all whom it may concern,

Be it known that l", PAUL RissMANN, a citizen of the United States, residing at Detroit, in the county of Wayne and State ot' Michigan, have Ainvented cert-ain new and useful Improvements in Automatic Stuffing Machines, of which Athe following is a specil .cationl This invention relates to automatic stuiiing machines, more particularly a machine for automaticallystuffing French plaits or straight pipes. Heretofore it has been customary to manufacture the upholstering for automobiles by sewing the top trimming inaterial to the burlap or other heavy material backing in straight lines of stitches, forming what is technically known as French plaits or straight pipes. These are also now -used with upholstering that has a leather facing or imitation leather facing. These have almost entirely supplanted the former type of upholstering by tufting. They are cheaper to manufacture, easier to keep clean and to many have an improved appearance' over theold tufting.

In manufacturing these straight pipes or French plaits it has been customary to stitch the trimming or acingmaterial to the bnrlap by folding the same and stitching the fold t0 the back. This forms straight pipes which nonY are stuffed by hand. Ordinarily a pair of channel strips ot' met l are used. a stri-p of cotton vv'adding is laid in the smaller width channel strip, the larger Width channel strip is then laid over this` and the tivo squeezed together and inserted in the straightpipe. The operator then' releases the pres. sure that holds the plaits together andy withdraws them in a separated condition` leaving the stuffing or cotton wadding in the pipe! v l It is the object of the present invention to do this ivorl; by a machine that is almost entirely automatic.

Suppoitewl on this 'traine-foin are n plurality of' hollow pipe eoreen, here Shown to be thirteen in n'nniliei: but obviously variable to suit conditions.

Tile nppe channel Strip rides on the outside ot' the core while the lowei channel strip o rifles on the inside of the core and tl'ie 'pine il engage down into the interim` of the core, 'thereby carrying the Wedding into the ein-e.

When the bei' 3 'one advanced sufficiently to the reel' to bring :i sti'ip of Wedding; the complete length of the trimming material or the pipes, the cam 14e (Figs. 1 and 1'?) on the rack 4bei 1 engefws the encl 16 of the Clntchesnifting rod 7c and throws tine clutch to the opposite side. The anni le can be nfl justed along its support to vai-y the travel oi' the feeding nets and accommodate this to trimming' of varying Width. This throws the clutch fork m to the right (ne vien/"esl in Fig. Q), bringing the driven clutch peet into engagement with the (living'olntcli' 'haar engag:v i' the clutch parts. 'it will be seen thai'l, cani ltTis less than haii'V the width of th am la. ilence when the cam 17 engages ilic rod only disengages the clutch parts.

Non' turning to Figs. 1T and 1S, it will he seen thai the clutch-shitting rod /c is secured by screus lll to the block 101. r1`his block 101 (detailed in Fig. 23) engages a head 2t) ot' the ririn 10U. This arm is detailed in Fig. 22. ri`his arni 100 is pivoted on the pin $21 which is secured to the fixed arm 2Q that is secured to the Fixed bar 102 by means of screws 23. This pivoted arm 1GO carries a depending pin "2#1 while the fixed arm 22 carries a. depending pin 25. The coiled spring engages between the two pins 9A. and and' is at its maximum extension when the two arms are in line. Hence When the pivoted arm 100 is thrown to either side ot a straight line position with respect to the fixed arm 22, this spring tends to. keep the piroted arm in that position. This is a familiar device for holding a pivoted member to either side of the center position. lt is used in this machine for 1the purpose oi holding the clutch parts together either in reverse or forward, and also for the purpose oi assisting in getting a quick snappy action when either the. clutch parts are thrown into engagement by hand or b v the cam 1li. The cani 17 engaging withy the end 18 of 'the clutch-shiiting` rod 7c holds the parts in neutral position. rhis cam 17 can be thin enough so as to cause the clutch parts to disengage but not assume an 'accurately center position as this would put the spring 26 into action ii' it were shifted by its center position. \So long' as the driven clutch part does not reach the center position then this spring 26 tends to hold the clutch parts disengaged in con'nection with the cam 17. The Li bracketsllQO secured to the bar 10Q guide the block 121 and limit the throw of the member n.

Referring "co Fig. 5, the details of the work ejecting; mechanism will be understood. 27 designates a table preferably constructed of maple board which has depending flanges Q8 that extend down at the sides and serve as guards. The diving chain 29 runs over a sprocket` 30 supported on the shaii y near the center oi' the machine'tliig. 2) and over a sprocket `wheel 31 on the shaft 32. rhis.

shaitI has a pair oi Jfriction wheels 33 on the end which protrude through the wooden table 2T and are adapted to be engaged by the iriction wheels Se carried on the frame ii which is hinged at 36 to the upright post (19in: il). '.lhis i'ranie is oounterbalancei'l by the lever arms 3S (Fig. l.) provided with the weights 'This trame (see Fil r11) roialablli' supports a shaft il which is provided with two pair; oi' sprocket wheeis #l1 over Vwhich the chains is ,ser

This chain is provided with a plurality of slats #lil fastened thereto, which slats carry the pins del. A sheet metal guard l5 is located over these slats and pins and has a lormation at the rear end such as shown in Figs. (5 and 7. The top sheet extends down in hoolelilre form to forni the bottom wall lil oi the device that serves to clear the pins lf-l 'troni the work. This element will be broadlyv referred to in the claims as means forl clearing the pins or the ejecting mechanism 'troni -the work. Another sheet of metal #le is riveted to the inside of the turnedeover top sheet '-l. These two sheets ltd and i6 meet at an acute angle and are slotted as at 49 to allow the pins ee to pass through these slots in drawing out of the work :is the pins start to turn by reason of the chain turning on the sprocket wheel at this point. These slotted sheets oi' metal 4:8 and e6 serve as a sort of prow to cut between the Work and the pins and allow the pins so clear themselves oi the work as vthey turn over-the sprocket wheel. This is obviouslg.7 an important` feature in the success ot' the ejecting mechanism for it assures the eject-ingI mechanism always ridding itselin loi' the work.

Ordinarily the ejectingl mechanism is held up out of the waz,v ot' the collapsible cores. The feeding bars leed the wedding into the cores, the cores are collapsed, the trimmingI material fitted over the cores, and then the pivoted framework which carries the ejecting pins is dropped down onto the table. 'lhe friction wheels on the traine engage the friction wheels on the. table and conse quently start the pins to traveling, thereby forcing the trimming material suitably packed with the wadding oli" from the cores. The pins engage the trimming material at a great number of points evenl)rr distributed over its entire surface, and when the traine carrying` the ejectinpins is dropped onto the trimming material, all these pins are impaled in the trimming material and studingand consequentlj,1 each exercises an equal pull in pulling oilI the. trimming; material.

Reifen-inv now to Fig. 2. it will he seen that there 1s a bar 50 that has plurality of toothed blades or pinchers 51 projecting down therefrom, one for each collapsible pipe core.l This bar 5() is bent into arms 52 at opposite ends which have their lower ends supported b v studs 53 on which is rotatably supported the roller 54. These studs 53 entln'ough the slots 55 in the plates 5S. These plates 56 are secured to the triangular gusset 5i' which is supported on the stud 58 of the pipe traine-work. Now referring ti Fins. 2l and il, it will be seen that this roller 5s.- is adapted to be dropped down when the reci( l resumes its forward position. The oller drops down the incline 59 on the rear i. end the bar 15. the coiled spring 60 pull.n
